In the mid 80's a cruiser of the U.S. navy put in to port in Catahegna,
Spain, for a week's shore leave. (Well, leave for the crew, not the cruiser.)
The first evening, the captain was more than a little surprised to receive the
following letter from an upper-class Spanish lady:

Dear Captain,

On Thursday, it will be my daughter's coming of age party. I would
like you to send four well-mannered, rich, unmarried officers. They
should arrive at 8 p.m. - One last point: no Jews - we don't like Jews.

Sure enough, at 8 on Thursday, the lady heard a rap at the door, which she
opened to find, in dress uniform, four exquisitely-mannered, wealthy, single,
BLACK officers. Her lower jaw hit the floor, but pulling herself together she
got out "There must be some mistake".

"Madam", said the first officer, "Captain Cohen doesn't make mistakes."
